Abstract
PURPOSE: To offer simple construction and smooth operation by integrating an actuator with a control-valve-running load motor, which feeds back the value of current pressure in EGR course of an EGR system to a flow control valve.
CONSTITUTION: An EGR system is constituted that a flow control valve 18 whose opening is controlled by a negative pressure motor 35 is equipped in an exhaust gas feedback course 7 communicating an exhaust gas passage with a suction passage 1. An actuator 37 including a pressure applied chamber 41 and reference pressure chamber 40 in communication with a space at a reference pressure near atmospheric pressure is mounted on said negative pressure motor 35, having a working rod 38 which moves according to pressure difference between those chambers. Suction negative pressure around a throttle valve 23 is sent through a negative pressure passage 46 to the negative pressure chamber 45 of said negative pressure motor 35. Throttle pressure of a throttle chamber 15 produced in a feedback course 13 is sent through a pressure applying passage 46 to the pressure applied chamber 41 of the actuator 37.
